Much of the MCAT’s science content is taught in the prerequisite courses themselves, so the cheapest MCAT prep is not forgetting what you already learned. Without review, course material fades in the months or years before the exam, and dedicated prep turns into relearning. Turning each lecture into spaced-repetition flashcards as you take the course keeps that content alive with a few minutes a day. When dedicated MCAT prep starts, you are reviewing, not starting over.

Distributed practice is one of the best-supported findings in learning research: spreading study over time improves long-term retention compared with massing it (Cepeda et al., 2006).

Focus on mechanisms and practice, not memorizing individual reactions. After each orgo lecture, write down the mechanisms covered, then test yourself on reagents, intermediates, and products until you can draw them without looking. Flashcards are well suited to reagent and named-reaction recall; short-answer questions work better for explaining why a reaction proceeds. NoteTube generates both from the lecture, and you can ask the AI to walk through a mechanism step by step using your professor’s explanation.

Re-reading feels productive but mostly builds familiarity, not recall. A landmark review of ten common study techniques rated only two as “high utility”: practice testing and distributed (spaced) practice, while re-reading and highlighting were rated low utility (Dunlosky et al., 2013). In a classic experiment, students who took a recall test on a passage remembered more of it a week later than students who spent the same time re-studying it, even though the re-studiers felt more confident right after (Roediger & Karpicke, 2006).

That is why NoteTube turns each lecture into flashcards scheduled with the SM-2 spaced-repetition algorithm and quizzes you can retake. Instead of re-reading a transcript the night before the exam, you answer questions drawn from the lecture across several days, which is the review pattern the research favors.
